WebService【WSDL】调用封装【已测试通过】

2.简单记录日志
/// <summary> /// 简单写入本地日志 /// </summary> public static class LogsHelper { public static void LogsWriteTxt(string strText, string strFileName = null) { try { if (strFileName == null || strFileName.Trim() == string.Empty) { strFileName = "Log" + DateTime.Now.ToString("yyyyMMdd") + ".txt"; } string getpath = AppDomain.CurrentDomain.BaseDirectory; if (Directory.Exists(getpath + "/日志信息") == false) { Directory.CreateDirectory(getpath + "/日志信息"); } string strFilePath = AppDomain.CurrentDomain.BaseDirectory + "手术状态回传日志\\" + strFileName; System.IO.StreamWriter sw = new System.IO.StreamWriter(strFilePath, true, System.Text.Encoding.Default); sw.WriteLine(strText); sw.Close(); } catch (Exception ex) { MessageBox.Show($"写入日志异常: { ex.Message}"); } } }
